Ok! Thanks! That is a word no normally seen in Film photography!
You have plenty of advice above. Ultimately, it is your trip and your gear.
I'll echo the advice for the Minolta system, even as you have 2 identical bodies. If one fails, you carry on with the other. If you look at my signature, you'll see I have most of my cameras in duplicate, for the same reasons of usability.
If weight isn't a problem, I would take the Pentax ME Super with the 20mm or the 35mm. In the last case, I'd leave the Minolta 35mm behind.
I used to have one of those Pentax years ago It is a very light camera and combined with the light short lenses as the 35mm and it is a good system for street photography.
Have a nice trip!
